INSTALLATION
NOTICE: This heater is intended
for use as supplemental heat.
Use this heater along with your
primary heating system. Do not
install this heater as your pri-
mary heat source. If you have a
central heating system, you may
run system’s circulating blower
while using heater. This will help
circulate the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
NOTICE: State or local codes may
only allow operation of this appli-
ance in a vented configuration.
Check your state or local codes.
WARNING: A qualified ser-
vice person must install heater.
Follow all local codes.
WARNING: If hand-held
remote accessory has been in-
stalled, make sure the selector
switch is in the OFF position
before installing heater.
WARNING: Before installing
in a solid fuel burning fireplace,
the chimney flue and firebox
must be cleaned of soot, creo-
sote, ashes and loose paint by a
qualified chimney cleaner. Creo-
sote will ignite if highly heated.
A dirty chimney flue may create
and distribute soot within the
house. Inspect chimney flue for
damage. If damaged, repair flue
before operating heater.
WARNING: Seal any fresh
air vents or ash clean-out doors
located on floor or wall of fire-
place. If not, drafting may cause
pilot outage or sooting. Use a
heat-resistant sealant. Do not
seal chimney flue damper.
